If your Outlook mailbox is filled with duplicate emails and contacts due to repeated imports or syncing issues, the built-in Cleanup tool often falls short because it only detects limited duplicates. A safer, effective approach is to use an automated duplicate removal tool designed specifically for Outlook data. Try the TrustVare Outlook Duplicate Remover, which is the best option in this situation. The software quickly scans PST or OST files using multiple parameters such as emails, contacts, calendar, notes, events, tasks, etc, finds duplicate items and removes them. The tool provided a preview option, which lets you review duplicate Outlook items before deleting them. The software is best for non-technical users because it has a simple interface for all non-technical users and they can use it without technical skills. It will run on all Windows OS versions like 11, 10, 8.1, 8, and 7. There is no need to download any other application like MS Outlook. You can try the free demo versions before buying this tool.
